Answer 1

The correct response is:

C. All available food was needed to support the war effort.

During World War I, there was a push for Americans to grow their own food to ensure that enough resources were available for soldiers and to support the war effort. This initiative included encouraging citizens to plant gardens, often referred to as "victory gardens," to supplement food supplies.
